Description

Technical Field

[0001] This utility model relates to the field of magnetic coupling transmission technology, specifically a high-temperature, high-pressure, large-diameter magnetic coupling transmission device. Background Technology

[0002] Magnetic coupling transmission devices can achieve contactless torque transmission, thus offering advantages such as maintenance-free operation, high efficiency and energy saving, stability and reliability, and overload protection for various load devices with different characteristics. Traditional mechanical transmission structures mainly include gear structures, pulley mechanisms, chain structures, and worm gear structures. These transmission mechanisms are directly and rigidly connected to the load, resulting in friction, wear, vibration, and noise during transmission. The permanent magnet eddy current speed controller is a non-contact speed control device based on the principle of electromagnetic induction. Its main function is to realize the motion and power transmission between the motor drive shaft and the load output shaft in a motion system. Its working principle is that when the input shaft drives the permanent magnet disk to rotate, a speed difference is created between the input and output shafts. The copper disk cuts the magnetic field lines emitted by the permanent magnet in the disk, generating an induced electromotive force and inducing eddy currents in the copper disk. These eddy currents generate a repulsive magnetic field, which interacts with the magnetic field generated by the permanent magnet, thereby achieving torque transmission between the two and driving the output shaft to rotate.

[0003] In existing technologies, magnetic coupling transmission devices are mostly fixedly connected to the chassis, and the chassis angle is not easy to adjust, which makes the device less flexible and adaptable. In some working conditions, the angle of the device cannot be adjusted, which can easily lead to a decrease in the efficiency of magnetic coupling transmission or a high level of energy loss. In addition, the inability to adjust the angle of the magnetic coupling transmission device makes maintenance and repair more complicated, resulting in excessive time consumption and difficulty in maintenance and repair.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing magnetic coupling transmission devices, which are mostly fixedly connected to a chassis, and the chassis angle is not easily adjustable, resulting in low flexibility and adaptability of the device. Furthermore, under certain working conditions, the inability to adjust the angle of the device can easily lead to reduced efficiency or energy loss in the magnetic coupling transmission. Additionally, the inability to adjust the angle of the magnetic coupling transmission device makes maintenance and repair cumbersome, resulting in excessive time consumption and difficulty in maintenance and repair. Therefore, this invention proposes a high-temperature, high-pressure, large-shaft-diameter magnetic coupling transmission device.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A high-temperature, high-pressure, large-diameter magnetic coupling transmission device includes a base; a cylinder is fixedly connected to the top of the outer wall of the base; a placement plate is rotatably connected to the top of the outer wall of the cylinder; a motor is fixedly connected to the top of the outer wall of the placement plate via a fixing block; a rotating shaft is provided at the output end of the motor; a driving rotor is fixedly connected to one end of the outer wall of the rotating shaft; a first placement disk is provided at the top of the outer wall of the placement plate; a driven rotor is disposed in the first placement disk, and the driven rotor matches the driving rotor; a first bevel gear is fixedly connected to the outer wall of the cylinder; a rotating rod is rotatably connected to the bottom of the outer wall of the placement plate via a square plate; a second bevel gear is fixedly connected to one end of the outer wall of the rotating rod, and the second bevel gear meshes with the first bevel gear; sprockets are fixedly connected to the other end of the outer wall of the rotating rod and the outer wall of the rotating shaft, and a pair of sprockets are connected by a chain.

[0008] Preferably, the rotating rod includes a fixed shell and an adjusting rod; the fixed shell is rotatably connected to the square plate; the top of the outer wall of the square plate is fixedly connected to the bottom of the outer wall of the placement plate; the outer wall of the adjusting rod is slidably connected to the inner wall of the fixed shell; an adjusting plate is rotatably connected to the outer wall of the adjusting rod; a first threaded rod is threadedly connected to one side of the outer wall of the square plate, and one end of the outer wall of the first threaded rod penetrates the square plate; the end of the first threaded rod penetrating the outer wall of the square plate is rotatably connected to one side of the outer wall of the adjusting plate.

[0009] Preferably, a second placement plate is fixedly connected to the top of the outer wall of the placement plate; a set of driving rotors is provided on the inner side wall of the second placement plate; a circular rod is fixedly connected to one end of the outer wall of the driving rotor; a third gear is fixedly connected to one end of the outer wall of the circular rod; a fourth gear is fixedly connected to the outer side wall of the rotating shaft, and the fourth gear meshes with the set of third gears; a set of driven rotors is provided on the inner side wall of the first placement plate, and the set of driven rotors is matched with the set of driving rotors.

[0010] Preferably, the top of the outer wall of the placement plate is provided with a vertical plate; a second threaded rod is threadedly connected to one side of the outer wall of the vertical plate, and one end of the outer wall of the second threaded rod penetrates through the vertical plate; a connecting plate is rotatably connected to one end of the second threaded rod penetrating through the outer wall of the vertical plate; one end of the outer wall of the connecting plate is fixedly connected to one side of the outer wall of the first placement plate.

[0011] Preferably, the top of the outer wall of the placement plate is provided with a pair of threaded grooves; the top of the outer wall of the vertical plate is threadedly connected with a pair of bolts, and the bottom of the outer wall of the pair of bolts penetrates the vertical plate; the pair of bolts are respectively matched with the pair of threaded grooves; the bottom of the outer wall of the first placement plate and the connecting plate are in contact with the top of the outer wall of the placement plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The rotating rod includes a fixed shell and an adjusting rod. By rotating the first threaded rod, which is threadedly connected to the square plate, the rotation of the first threaded rod causes it to move, which in turn causes the adjusting plate to move. This disengages the second bevel gear from the first bevel gear. When the motor drives the rotating shaft to rotate, only the rotor rotates, while the placement plate does not change its angle. When the angle needs to be changed, simply reverse the first threaded rod. Furthermore, when the first and second bevel gears disengage, workers can use other tools to fix the placement plate, preventing it from shifting. This makes the device more flexible and practical.

[0014] 2. When the motor drives the rotating shaft to rotate, the rotating shaft drives the fourth gear. Because the fourth gear meshes with a set of third gears, the rotation of the fourth gear drives the rotation of the set of third gears, which in turn drives the circular rod to rotate. The circular rod then drives the second drive rotor to rotate, which in turn drives the second driven rotor to rotate through magnetic force. This allows the device to drive not only the first driven rotor to rotate, but also a set of second driven rotors, thereby maximizing the use of the motor and minimizing energy consumption when driving multiple devices.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please see Figures 1-5As shown, a high-temperature, high-pressure, large-diameter magnetic coupling transmission device includes a base 1; a cylinder 2 is fixedly connected to the top of the outer wall of the base 1; a placement plate 3 is rotatably connected to the top of the outer wall of the cylinder 2; a motor 4 is fixedly connected to the top of the outer wall of the placement plate 3 via a fixing block; a rotating shaft 5 is provided at the output end of the motor 4; a drive rotor 6 is fixedly connected to one end of the outer wall of the rotating shaft 5; a first placement disk 7 is provided at the top of the outer wall of the placement plate 3; a driven rotor 8 is provided inside the first placement disk 7, and the driven rotor 8 matches the drive rotor 6; a first bevel gear 9 is fixedly connected to the outer wall of the cylinder 2; a rotating rod 11 is rotatably connected to the bottom of the outer wall of the placement plate 3 via a square plate 10; a second bevel gear 12 is fixedly connected to one end of the outer wall of the rotating rod 11, and the second bevel gear 12 meshes with the first bevel gear 9; a sprocket 13 is fixedly connected to the other end of the outer wall of the rotating rod 11 and the outer wall of the rotating shaft 5, and a pair of sprockets 13 are connected by a chain 14, which drives the rotating shaft 5 to rotate via the motor 4. Shaft 5 drives drive rotor 6, which in turn drives driven rotor 8 to rotate via magnetic force. When it is necessary to change the direction or angle of placement plate 3 and driven rotor 8, sprockets 13 are fixedly connected to the other end of the outer wall of rotating rod 11 and the outer wall of rotating shaft 5. A pair of sprockets 13 are connected by a chain 14, which causes rotating shaft 5 to drive rotating rod 11 to rotate via sprockets 13 and chain 14. This causes rotating rod 11 to drive second bevel gear 12 to rotate. Since second bevel gear 12 meshes with first bevel gear 9 and first bevel gear 9 is fixed on cylinder 2, the rotation of second bevel gear 12 will follow the rotation of first bevel gear 9, thereby causing rotating rod 11, square plate 10, and placement plate 3 to change direction or angle. This makes it more convenient and flexible to adjust the angle of the device, thereby reducing energy loss or improving the efficiency of magnetic coupling transmission. Furthermore, the device is easy to maintain or repair by changing the angle of placement plate 3 during maintenance or repair.

[0024] A second placement plate 17 is fixedly connected to the top of the outer wall of the placement plate 3; a set of drive rotors 18 is provided on the inner side wall of the second placement plate 17; a circular rod 19 is fixedly connected to one end of the outer wall of the drive rotor 18; a third gear 20 is fixedly connected to one end of the outer wall of the circular rod 19; a fourth gear 21 is fixedly connected to the outer side wall of the rotating shaft 5, and the fourth gear 21 meshes with the set of third gears 20; a set of driven rotors 22 is provided on the inner side wall of the first placement plate 7, and the set of driven rotors 22 are respectively matched with the set of drive rotors 18. When the rotating shaft 5 is driven to rotate by the motor 4, the rotation... The moving shaft 5 drives the fourth gear 21. Because the fourth gear 21 meshes with a set of third gears 20, the rotation of the fourth gear 21 drives the rotation of the set of third gears 20, which in turn drives the circular rod 19 to rotate. The circular rod 19 then drives the second drive rotor 18 to rotate, which in turn drives the second drive rotor 18 to rotate through magnetic force. This allows the device to not only drive the first driven rotor 8 to rotate, but also drive the second set of driven rotors 22 to rotate, thereby maximizing the utilization of the motor 4 and minimizing energy consumption when driving multiple devices.

[0025] A vertical plate 23 is provided at the top of the outer wall of the placement plate 3; a second threaded rod 24 is threadedly connected to one side of the outer wall of the vertical plate 23, and one end of the outer wall of the second threaded rod 24 passes through the vertical plate 23; a connecting plate 25 is rotatably connected to one end of the second threaded rod 24 that passes through the outer wall of the vertical plate 23; one end of the outer wall of the connecting plate 25 is fixed to one side of the outer wall of the first placement disk 7. By rotating the second threaded rod 24, since the second threaded rod 24 is threadedly connected to the vertical plate 23, the rotation of the second threaded rod 24 causes the second threaded rod 24 to move, the movement of the second threaded rod 24 causes the connecting plate 25 to move, and the connecting plate 25 causes the first placement disk 7 to move, thereby adjusting the distance between the driven rotor 8 and the driving rotor 6. This allows the device to adjust the distance between the driven rotor 8 and the driving rotor 6 according to the current situation, making the magnetic coupling transmission efficiency of the driven rotor 8 and the driving rotor 6 better, thereby further facilitating the reduction of energy loss.

[0026] The rotating rod 11 includes a fixed housing 111 and an adjusting rod 112; the fixed housing 111 is rotatably connected to the square plate 10; the top of the outer wall of the square plate 10 is fixedly connected to the bottom of the outer wall of the placement plate 3; the outer wall of the adjusting rod 112 is slidably connected to the inner wall of the fixed housing 111; an adjusting plate 15 is rotatably connected to the outer wall of the adjusting rod 112; a first threaded rod 16 is threadedly connected to one side of the outer wall of the square plate 10, and one end of the outer wall of the first threaded rod 16 penetrates the square plate 10; the end of the first threaded rod 16 penetrating the outer wall of the square plate 10 is rotatably connected to one side of the outer wall of the adjusting plate 15. The rotating rod 11, including the fixed housing 111 and the adjusting rod 112, is rotated by rotating the first threaded rod... 16. Because the first threaded rod 16 is threadedly connected to the square plate 10, the rotation of the first threaded rod 16 causes the first threaded rod 16 to move, which in turn causes the first threaded rod 16 to move the adjusting plate 15, which in turn causes the adjusting plate 15 to move, thereby disengaging the second bevel gear 12 from the first bevel gear 9. Thus, when the motor 4 drives the rotating shaft 5 to rotate, only the rotor 6 rotates, while the placement plate 3 does not change its angle. When it is necessary to change the angle, simply reverse the first threaded rod 16. Furthermore, when the first bevel gear 9 and the second bevel gear 12 disengage, the operator can use other tools to fix the placement plate 3, preventing the placement plate 3 from shifting, making the device more flexible and practical.

[0027] The top of the outer wall of the placement plate 3 has a pair of threaded grooves 26; the top of the outer wall of the vertical plate 23 is threaded with a pair of bolts 27, and the bottom of the outer wall of the pair of bolts 27 penetrates the vertical plate 23; the pair of bolts 27 are respectively matched with the pair of threaded grooves 26; the bottom of the outer wall of the first placement plate 7 and the connecting plate 25 are in contact with the top of the outer wall of the placement plate 3. By rotating the bolts 27, the bolts 27 are moved out of the threaded grooves 26, at which point the vertical plate 23 is released from the placement plate 3. Then the vertical plate 23, the connecting plate 25 and the first placement plate 7 are removed, and a new first placement plate 7 is placed, so that the equipment can operate normally. When the driven rotor 1 8 or the driven rotor 2 22 is damaged, this device can solve the problem by replacing the first placement plate 7, so as not to delay the operation of the equipment. Moreover, the ease of installation and disassembly of the first placement plate 3 makes the first placement plate 7, driven rotor 1 8 or driven rotor 2 22 easy to clean and maintain.

[0028] Working principle: The motor 4 drives the rotating shaft 5 to rotate, which in turn drives the drive rotor 6. The drive rotor 6 then drives the driven rotor 8 to rotate through magnetic force. When it is necessary to change the direction or angle of the placement plate 3 and the driven rotor 8, sprockets 13 are fixed to the other end of the outer wall of the rotating rod 11 and the outer wall of the rotating shaft 5. A pair of sprockets 13 are connected by a chain 14. The rotating shaft 5 drives the rotating rod 11 to rotate through the sprockets 13 and the chain 14. The rotating rod 11 drives the second bevel gear 12 to rotate. Since the second bevel gear 12 meshes with the first bevel gear 9 and the first bevel gear 9 is fixed on the cylinder 2, the second bevel gear 12 rotates along with the first bevel gear 9, thereby driving the rotating rod 11, the square plate 10, and the placement plate 3 to change direction or angle. This makes it convenient and flexible to adjust the angle of the device, thereby reducing energy loss or improving the efficiency of magnetic coupling transmission. Furthermore, the device is easy to maintain or repair by changing the angle of the placement plate 3.

[0029] When only the rotor 6 needs to be driven to rotate, and the angle of the placement plate 3 does not need to be changed, the rotating rod 11 includes a fixed shell 111 and an adjusting rod 112. By rotating the first threaded rod 16, which is threadedly connected to the square plate 10, the rotation of the first threaded rod 16 causes the first threaded rod 16 to move, which in turn causes the adjusting plate 15 to move. This causes the second bevel gear 12 to disengage from the first bevel gear 9, thereby causing the motor 4 to drive the rotating shaft 5 to rotate. Only the rotor 6 is driven to rotate, and the angle of the placement plate 3 does not change. When the angle needs to be changed, the first threaded rod 16 can be reversed. Furthermore, when the first bevel gear 9 and the second bevel gear 12 disengage, the operator can use other tools to fix the placement plate 3 to prevent it from shifting, making the device more flexible and practical.

[0030] When multiple devices need to be driven to maximize the use of motor 4, the rotating shaft 5 is driven by motor 4. The rotating shaft 5 drives the fourth gear 21. Since the fourth gear 21 meshes with a set of third gears 20, the rotation of the fourth gear 21 drives the set of third gears 20 to rotate. The third gears 20 drive the circular rod 19 to rotate. The circular rod 19 drives the second drive rotor 18 to rotate. The second drive rotor 18 drives the second driven rotor 22 to rotate through magnetic force. This device can not only drive the first driven rotor 8 to rotate, but also drive the second driven rotor 22 to rotate, thereby maximizing the use of motor 4 and minimizing energy consumption when driving multiple devices.

[0031] When it is necessary to adjust the distance between the driven rotor 8 and the driving rotor 6 to improve the transmission efficiency of the driven rotor, the second threaded rod 24 is rotated. Since the second threaded rod 24 is threadedly connected to the vertical plate 23, the rotation of the second threaded rod 24 causes the second threaded rod 24 to move. The movement of the second threaded rod 24 causes the connecting plate 25 to move, which in turn causes the first placement disk 7 to move. This adjusts the distance between the driven rotor 8 and the driving rotor 6 according to the current situation, improving the efficiency of the magnetic coupling transmission between the driven rotor 8 and the driving rotor 6, thereby further facilitating the reduction of energy loss.

[0032] When the driven rotor 1 8 or driven rotor 22 is damaged, the bolt 27 is rotated to move it out of the threaded groove 26. At this time, the vertical plate 23 is released from the placement plate 3. Then, the vertical plate 23, the connecting plate 25 and the first placement plate 7 are removed, and a new first placement plate 7 is placed to allow the equipment to operate normally. When the driven rotor 1 8 or driven rotor 22 is damaged, the problem can be solved by replacing the first placement plate 7, so as not to delay the operation of the equipment. The ease of installation and disassembly of the first placement plate 3 makes the first placement plate 7, driven rotor 1 8 or driven rotor 22 easy to clean and maintain. In addition, because the magnetic coupling transmission device is made of high temperature and high pressure resistant materials to a certain extent, the device has high temperature and high pressure resistant function.
